You’re correct, but states are looking for UL 3700 compliance, which extends current anti islanding inverter protection requirements to GFCI intelligence and circuit overload protection (you can overload the branch circuit without the breaker tripping, for example). Intelligent EV chargers support these protections, this is the generation version of protections mentioned.
Thanks for the links. I hope they don't make it difficult to add batteries to these systems. You can pick up five plus kilowatt rack mount batteries relatively cheaply. It would be unpleasant if they only permitted the expensive no-user-serviceable-parts battery boxes like jackery.
